Historia, it's when it gets to Poster 3 type commenting - and it always does because those threads are that way 'by design'.
TheClaws, I don't think posters do post in AIBU for support and if they do, they're quickly herded off. There are a lot of threads that would irritate me and I never even open them. If I make the mistake of opening them, I immediately hide them, we can all do that.
BIWI, I've explained (perhaps not well) about the direction that some threads take. The last SPAG that was moved to Pedants' Corner was really insulting in some posts. Not to me, to posters 'guilty' of literacy transgressions and it went beyond just 'sneery'.
It's the same tired format of lazy 'let's have a bunfight' thread, exactly like the horrible "AIBU to think that people shouldn't have dirty houses"... the OP of that thread name-changed because she knew it was going to cause upset - actually said so. What a twattish poster that one is who is probably back in her usual name now, posting alongside posters that have no idea what an inadequate person she is. She wasn't on her own because she had lots of willing and bile-filled posters falling over themselves to agree and give examples and ramp it up. The OP got what she wanted, at the expense of many. That thread was vile.
I was looking at the butter/spread thread just now, interested in what posters think of it and even though there's a definite 'split between who likes what, it's not judgemental. Not all threads have to become bunfights, but some are posted for that purpose or at least in the hope of it.
What you said, TheClaws about traffic - and picking up your point, BIWI about wanting a rant... how would a new board prevent that? I mean, if you have a dog and you want to chat about him you'd probably wander over to 'The Doghouse' because you'd find other dog-lovers there. How would a new board encroach? Presumably, if you'd got a bee in your bonnet about some SPAG issue, you'd hot-foot it over to the new board and find other people ranting about the same or similar and you'd presumably be in your element. Why the need for it to be on the main board where you will insult/diminish posters, given that the thread will not just stay at Poster 1 or 2 level because it never, ever does?
I know you think that I'm policing MN, BIWI or trying to. I'm really not. Mostly I read and move on without posting anything or reporting. We could all do that. We could all find something else to do rather than frequent Mumsnet too and I give myself holidays quite often. All of us posting here are reporting trolls and calling out bigotry, racism, disablism, etc. and we're expected to do that, aren't we? It shows that we don't think that's acceptable and it shows solidarity for the person/group being picked on.
Well, given that we don't know whether a poster falling foul of SPAG has just made a typo or whether they have dyslexia, English not their first language, other reason - it's not reasonable to chance it, is it?
Even if they are just 'incorrect', it's rude to correct adults that haven't asked for that correction. The Pedants' Corner is where I go when I want to check something and I learn new words there or on the main boards just by seeing the words posted. I don't have to say anything and the poster isn't drawing anybody's attention to them, it's just part of the posts.
Anyway, I started this thread as it was suggested on the current SPAG thread. MNHQ are the only 'police' here, I've got no interest in acting like a 'board monitor', I'm anything but. I've had my fair share of 'Mumsnet Calling' e-mails and posts deleted when I've posted like a twat, I'm sure, despite my best intentions, there will be more.
